I am aware of the existance of this package. Note that I want to be able to
also cleanup the space that the task object itself uses.
Thus when I have a pointer to some task type there is actually some space
allocated for the task itself. I want to free that space also. Normally
that space
is simply allocated with a new.
Note that whatever you do, the task itself can not do that because it is
very dangeraous to do that. After disposal the space might still be
refferenced
by the task itself.
So my question is how to make this program work:
   task type xtask;
   task body xtask is
   begin
       null;
   end xtask;
   type pxtask is access xtask;

   for i in integer'range loop
      declare p:pxtask:=new xtask;
   end loop;
The program can be made working when doing a lot of adminstrating
on the pointers to the objects created in the main program.
I actually want to deallalocate them in the task itself when they complete.

Wiljan
